Linux and Red Hat Linux Certification
Red Hat High Availability Clustering (RH436)
Deploy reliable, available critical production services in a high availability cluster.
In the Red Hat High Availability Clustering (RH436) course, you will learn how to provide highly available network services to a mission-critical enterprise environment through the deployment and management of shared storage and server clusters. Created for senior Linux system administrators, this 4-day course strongly emphasizes lab-based activities.
You will set up a cluster of systems running the Pacemaker component of the Red Hat Enterprise Linux High-Availability Add-On, and deploy Linux-based services such as web servers and databases on that cluster. Cluster storage components from the Resilient Storage Add-On are also covered; installations and applications that require multiple cluster nodes can access the same storage simultaneously. This includes Logical Volume Manager (LVM) Shared Volume Groups, Red Hat Global File System 2 (GFS2), and Device-Mapper Multipath.
This course is based on Red Hat Enterprise Linux 8.3.

Prerequisites
If you want to take this course without the exam (RH436) and have not earned your RHCE® certification, you can confirm that you have the necessary knowledge by passing the online skills assessment.
Upon completion of this course, students will be able to:
- Install and configure a Pacemaker-based high availability cluster.
- Create and manage highly available services.
- Troubleshoot common cluster issues.
- Work with shared storage (iSCSI) and configure multipathing.
- Implement Logical Volume Manager (LVM) in cluster-aware configurations.
- Configure GFS2 file systems on storage shared by multiple nodes.
Creating High Availability Clusters
Create a basic high availability cluster.
Managing Cluster Nodes and Quorum
Manage node membership in the cluster and describe how that impacts cluster operation.
Isolating Malfunctioning Cluster Nodes
Isolate unresponsive cluster nodes to protect data and recover services and resources after a failure.
Creating and Configuring Resources
Create basic resources and resource groups to provide highly available services.
Troubleshooting High Availability Clusters
Identify, diagnose, and fix cluster problems.
Automating Cluster and Resource Deployment
Deploy a new high availability cluster and cluster resources using Ansible automation.
Managing Two-node Clusters
Operate two-node clusters, identifying and avoiding issues specific to a two-node cluster configuration.
Accessing iSCSI Storage
Configure iSCSI initiators on your servers to access block-based storage devices provided by network storage arrays or Ceph storage clusters.
Accessing Storage Devices Resiliently
Configure resilient access to storage devices that have multiple access paths.
Configuring LVM in Clusters
Select the correct LVM configuration for use in your cluster, and configure and manage it.
Providing Storage with the GFS2 Cluster File System
Provide tightly coupled shared storage that can be accessed by multiple nodes simultaneously, using the GFS2 cluster file system.
Eliminating Single Points of Failure
Identify and eliminate single points of failure in your cluster to decrease risk and increase average service availability.
